Figure 3 is a sectional view on the line 33 of 40 FigureiZ;

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A desig- 45 nates generally the platform of a grain binder of conventional form equipped at the lead edge thereof with a sickle and guard l0 and H, respectively, while upon the platform rearwardly of the said sickle and its guard and operating 50 parallel therewith is an endless conveyor or apron l2 which is an adjunct of the grain binder in the feed of the cut material delivered upon this apron or conveyor and to this platform is applied the attachment constituting the present inven- 5 tion and hereinafter fully described.

The attachment comprises'apair of angle bars [3, theseybeing suitably fastened to the under side of the platform A for disposition in spaced parallel relation to each other and projecting forwardly of the sickle l0 properly spaced from .5 one end of said platform. The-angle bars are preferably of L+form in cross section ands-are invertedwith-the laterally flangededges l4 thereofoutermost'from between; said bars. Secured to these bars 1-3 are forwardly tapered substantially triangular shaped side panels or plates 15 forming a-way ;l 6=therebe tween, the lower edges 11; of these panels or plates l5 are disposed in cross relation to thegroundsurface. I

, (Jarried at the inner faces of the panels or 15 plates 15 are forwardly inclined endless gathering chains l8 having provided on selected linkstheree of ,gathering spursglB, Thechains 18 are trained over ,power and ,guidefsprockets 20 and 2l, respectively. The drivevsprockets 2llare fixed to 20 stud shafts22, these being suitably journaled and carried bysaid panels or plates l5. I

In rear of the chains l8 upon the panels or plates" 15 injuxtaposition to the high inner ends thereof are reverselyinclined endless transfer chains 23 trained over power and guide sprockets 24' and 25, respectively, suitably journaled and supported from the panels or plates IS. The power sprockets. arefixed to shafts 26 which aresuitably journaled and through meshing pinions or gears 21 are connected with operating shafts 28', these being journaled in bearings 29 .fixed to theunderside of the frame-A and extend in close parallel relation -to :each other fore and aft, of said frames These shafts, 28 at theaft 5 ends thereof carry meshing gears 30 so that said shafts will rotate in unison and in reversedirections to :each other while one of the shafts 28 through chainand sprocket COIIIIBCUlOIlSQ'I and :32. re c v lms dr vead rectw fromthe binder 40 mechanism v(not shown).

The shafts 22 and 26 through chains 33, sprockets 34 and gears 35, respectively, are connected with each other for the proper driving of the gathering and transfer chains [8 and 23, respectively. The chains 23 at certain links thereof are provided with spurs 36 to assure the transfer of material onto the apron or conveyor l2 when such material, such as soy beans, have been out after being gathered in a field by the chains 58 in the way l6 between the panels or plates l5, the cutting of the material being had by the sickle l0 while in operation.

The way l6 between the panels or plates [5 affords a throat for the material and directs the latter to the sickle ID on advancement of the binder through a field.

The chains l8 at their lowermost ends are in close proximity to the lower edges H of the panels or plates l and are rearwardly of the smaller forward ends of said panels or plates so that the growing soy beans can be gathered into the throat to be in the path of the sickle 0 for the severing of the beans and the transfer of such severed material onto the apronprxcon veyor l2. :g

Directly over the chains I8 and 23 and carried by the panels or plates l5 are inwardly inclineddg, shed or guard planks 31, these being coextensive 7 simultaneously with each other. fi ln anattachment for a grain binder, a broad cast header and a sickle at its lead edge with the upper edges of said panels-or-plates and'have the forward rounded ends 38 affording;

a relatively wide entrance at the tips 39 of said panels or plates l5 to the way l6 therebetwen J to increase the gathering area at the point of the said tips 39 of the attachment. The planks 31 avoid entanglement of the beans or material gathered by the chains l8 and transferred by the chains 23 onto the apron or conveyor l2 during the working of the attachment to the binder. v

Suitable bearings 40 and 4|, respectively, are provided for the mountings of-the shafting and gearing of the attachment and these bearings are carried by the panels or plates 1 5 as will be clearly apparent from Figures 2 and 3 of the drawings.

The bars [3 are separatclyfastened to the frame A and likewise the bearings 29 are detachable therefrom so that the attachment can be conveniently removed from the binder when it is desired that the latter be'utilized as a grain binder. 1 l r The rear ends of thepanels or plates I5 are cut into at 42 to form a clearance for the sickle Ill and to have the transfer chains 23 overlap for the required distance the said apron or conveyor l2 forthe transfer of the cut. material thereonto. I

The planks 31 are separated throughout their extent to effect a lead slot centrally of the way l6 for the gathered material when being directed by the chains l8 and the transfer of the severed material when out by thesickle ll] of the binder onto the apron or conveyor l 2 thereof.

The frame A as is customary has arranged at its outer end a wheel 43 which travels uponthe ground in the advancement'of the binder and such wheel may be vertically adjusted relative to said frame to have-the latter at the proper or desired height from the ground surface and also the sickle thereon.

What is claimed is:

1. In an attachment for a grain binder, a broad cast header and a sickle at its lead edge'comprising a pair of-angle bars secured to the under side of the header in spaced parallel relation to each other and extended forwardly of the lead edge thereof, forwardly tapered substantially triangular shaped panels secured perpendicularly to said bars to elfect a way therebetween, forwardly inclined endless gathering chains supported for operation in the way by said panels and having gathering spurs, rearwardly inclined extensions on said panels and overhanging the header, endless transfer .chains arranged: next to the gathering chains and held rearwardly inclined by said extensions and in overhanging relation to the header, and means operated by the binder for driving the gathering and transfer chains comprising a'pair of angle bars secured to the under. side of the header in spaced parallel relati on'to each other and extended forwardly of the lead-edge thereofw forwardly 'tapere'd substantially triangular shapedpanels secured perpendicularly to said bars to eifecta way therebetween; forwardly inclined. endless gathering chains supp'ortedfor operation in the way by said panels and having gathering spurs, rearwardly inclined extensions 1 on said panels and overhanging theheader, endless transfer chains arranged neXtto the gathering chains and held rearwardly inclined by said extensions and in overhanging relation to the header, a pair of power shafts arranged below the header and extending in the direction of the lead end thereof, and driven connections between said power shafts and the gathering and transfer chains for operation thereof.

'- 3. In an attachment for a grain binder, a broadcast header and a sickle at its lead edge comprising a pair of angle bars secured to the under side of the header in spaced parallel-relation to each other and-extended forwardly of the lead edge thereof, forwardly tapered substantially triangular shaped panels secured perpendicularly to said bars toeffect a way therebetween; forwardly inclined endless gathering chains supported for operation in the wayby saidpanels and having gathering spurs, rearwardly'inclined extensions on said panels and overhanging the header, endless transfer chains arranged next to the gathering chains and held rearwardly inclined by said extensions and in overhanging relation to the header, a pair of power shafts arranged below the header and extending in the direction of the lead end thereof, driven connections between said power shafts and the gathering and transfer chains for operation thereof, and guards arranged on said panels and overhanging the said chains.
